Overview
In the simplest terms, computer vision is the discipline of "teaching machines how to see." This field dates back more than fifty years, but the recent explosive growth of digital imaging and machine learning technologies makes the problems of automated image interpretation more exciting and relevant than ever. This course will cover the foundations of computer vision, including basic image processing, feature extraction and matching, image formation, and 3D structure recovery. The focus will be largely on mathematical frameworks and "classical" problem formulations and techniques, not on state-of-the-art deep learning systems. Students primarily interested in deep learning should consider taking CS 444.Prerequisites: Knowledge of linear algebra, calculus, probability and statistics. Python programming experience and previous exposure to image processing and numerical optimization are highly desirable. Knowledge of deep learning is helpful, but not required.
Recommended textbooks:
- Computer Vision: A Modern Approach by David Forsyth and Jean Ponce (2nd ed.)

- Foundations of Computer Vision by Antonio Torralba, Phillip Isola, and William Freeman
- Programming assignments: 50%
- Five MPs, done individually, in Python
- Final project: 30%
- Groups of two to five; deliverables include proposal, intermediate progress report, final report
- Unit quizzes: 20%
- Three or four multiple-choice online quizzes on the four units from the syllabus below
- Participation: up to 3% extra credit
- Students can get extra credit for actively participating in class, on Piazza, or during office hours
